DRINKING-FAUOET.

Application filed August 29, 1919. Serial No. 320,642.

To all whom z't mag concern:

Be it known that I, ERNEST E. /VANGELIN, a citizen of the United States,residing at Belleville, in the county of St. Clair and State ofIllinois, have invented certain new and useful Improvements in DrinkingFaucets, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming a part hereof.

The present invention is directed to ime provenien js in drinkingfaucets commonly known as bubblin cups, and particularly to that type inwhich the stream issues from the cup at an incline to prevent anyportion of the water intercepted by the mouth of the drinker fromdropping back on the cup. One of the objects sought by the presentimprovement is to provide the faucet with a suitable hood or equivalentformation which will compel the drinker to so position his mouth as tokeep the lips from actual contact with the faucet when drinking. Afurther object is to provide the faucet with suitable means forregulating the force and size of the stream furnishing the water to bedrunk, such means being out of reach of persons disposed to tamper withthe regulating device. A further object is to construct a faucet orbubbling cup which will be highly serviceable, hygienic, and attractive,and presenting a neat appearance, and one possessing further and otheradvantages better apparent from the following detailed description inconnection with the accompanying drawings in which Figure 1 represents aside'elevation of the faucet; Fig. 2 is a front elevation; Fig. 3 is avertical section in the plane of the discharge passage-way taken on theline 3- of Fig. 2; Fig. 4 is a top plan of the faucet; Fig. 5 is ahorizontal cross-section on the line 5-5 of Fig. 3; Fig. 6 is ahorizontal cross-section on the line 6-6 of Fig. 3 with parts brokenaway; and Fig. 7 is a side elevation of the faucet on a smaller scaleshowing the same in actual operation.

Referring to the drawings, 1 represents a cup formed with a flaring base2, the latter being provided with an outer enlarged screw socket a, forattaching the cup to a suitable water supply pipe P, and an innerreduced screw-threaded bore Z) in which operates the tubular screw stemor regulator valve 3,

one end of which is closed by a head 3 provided with a transverse groove12 for applying a screw driver thereto. The tube 3 is provided with aplurality of peripheral openings or ports 0 adjacent the inner face ofthe head. 8 which serve to establish communication between the source ofwater supply (pipe P) and the chamber of the cup 1. It is clearlyapparent from the drawings that the quantity of water admitted into thecup can be regulated by adjusting the position of the openings 0 acrossthe plane of the bottom of the chamber of the cup, a full exposure ofthe openings above said bottom admitting a maximum quantity of water anda partial exposure a less quantity; and if the valve 3 be screwed towardthe socket a suificiently to entirely close the ports 0 by the walls ofthe bore 6, the water will be entirely out off. Of course the ports 0are disposed in a common plane transverse to the axis of the regulatortube 3, so that the several ports are all aifected alike with anymovement imposed on the regulator.

The top of the cup 1 is closed by a screw cap or lid 4 which, when fullydriven home, shoulders a ainst the edge of the cup, the top of thescrew-cap being more or less dome-shaped as shown. The said screwcap isperforated by an inclined passageway it cutting across the common axisof the cap and 'cup whereby the same dis charges the water from the cupto one side of said axis. Formed with the screw-cap 4t and projectingabove the same, and contoured to protect the top and sides of the waterstream S issuing from the passageway h, is a hood or cowl 5', the samebeing spaced from the stream on all sides as clearly obvious from thedrawings (Figs. 2, 3). The hood is substantially U-shaped incross-section and practically envelops the screw-cap 4 circumferentiallyover an arc of substantially one hundred and eighty (180) degrees ormore, thereby preventing approach to the bottom portions of the stream Sfrom the rear or sides. The side walls of the hood are disposedsymmetrically on opposite sides of the passage-way h and the waterstream S issuing therefrom. The hood as a whole is so shaped as toprevent the application of the lips of the drinker to the outer surfaceof the screwcap 4. The hood may be said to terminate Patented July 27,1920.

at the top in a reduced extension 5 which,

as clearly shown in Fig. 7, prevents the lips. L of the drinker frombeing applied to the top or the lower portion of the stream S, theshortest distance between the stream and the lips when resting againstthe extension 5 being too great to permit the lips to reach the stream,(dotted position Fig. 7). The consequence is that since the stream cannot be approached or engaged by the lips from the sides or rear; andsince the hood extension 5 arrests the lips before they can be appliedto the lower portion of the stream from the top, the drinker will beforced to attack the stream at some point in front of the hood away fromthe cup, say substantially at a point designated by in Fig. 7. At thispoint the lips of the drinker will be entirely out of contact with anyportion of the bubbler or faucet, the overflow from the mouth fallingout of range of the cup, thereby making the cup perfectly hygienic.

It will be seen from the drawings that the lid or screw-cap 4 hasconsiderable thickness thereby imparting to the passage-way 71.considerable length, the passage-way thus elongated operating to givethe stream definite direction without material spreading whiletraversing the space bounded by the hood, so that a coherent stream isdirected into the mouth. The intensity of the stream is of courseregulated by the valve 3 which determines the rate of influx of thewater into the cup 1 as above described. The said valve is out of reachof mischievous persons,

being protected by the lid 4 which after being driven home is secured tothe cup walls by a set screw 6 driven flush with the outer face of thecup. The latter is provided with the usual relief port 0 which causesthe water to be forced downward in the event some one should, close thedischarge end of the passage-way h as well understood in the art, thisport being too small to allow any material quantity of water to leak outunder normal operating conditions. The faucet may obviously be changedin many details without involving a departure from the nature or spiritof the invention. In the presentembodiment of the communicating at oneend with a suitable source of water supply, a screw-cap or lid closingthe top of the cup, said'lid being formed with an elongated openendedpassage-way communicating respectively with the interior andoutside of the cup, said passage-way being disposed across the axis ofthe cup and lid, a regulator valve interposed between the water supplysource and chamber of the cup, and a hood or cowl leading from the outerboundaries of the lid and extending circumferentially partially aroundthe lid to envelop the sides and top portions of the bottom of thestream issuing from the passage-way, the hood terminating at the top ina reduced portion extended in the line of the axis of the cup to a pointto intercept the lips of the drinker approaching the stream from thetop, the sides of the hood preventing approach of the stream from thesides.

2'. In a drinking faucet of the character described and discharging astream at an incline to the vertical, a hood encompassing the sides andtop of the bottom of the stream so dischar ed to prevent approach to thestream from three directions, and a reduced extension leading from thehood upwardly to a point su'llicient to prevent the lips when resting onthe extension from engaging the stream, said extension being in thegeneral direction of the vertical axis of the faucet and to one sideofthe same.

In testimony whereof I afiix my signature in presence of two witnesses.
